I guess I see "Church" different. Paul describes a real New Testament Church as one that has the truth.
15 But if I tarry long , that thou mayest know how thou oughtest to behave thyself in the house of God, which is the church of the living God,
the pillar and ground of the truth. 1 Tim 3:15
See? A Church group is not recognized just because it has a building to meet in with a name over the door. Rather it is recognized because it is the pillar and ground of the truth. When false doctrine is being taught nothing says we are to compromise with it. Just because a Pastor says he is one means little if he is not moving in Gods agenda.
